According to Third Man, additional details will be revealed in the coming weeks. However, Jay-Z seemed to let the cat out of the bag during a recent interview with Hot 97, telling Angie Martinez that “Open Letter” will be available as a “playable letter.” He explained, “It’s in a letter… you can play the letter… it’s amazing. You open the letter, and you can actually play the card.”

Jay-Z and White’s history dates back several years when reports surfaced of a collaborative track called “Ray Bans” that has yet to see release. Earlier this year, the two partnered for the vinyl release of The Great Gatsby soundtrack, for which Jay-Z served as executive producer.
